How to use dinotefuran-containing household insecticide spray to control inchworms?

How to use dinotefuran-containing household insecticide spray to control inchworms? Dinotefuran-containing sprays are highly effective against inchworm larvae. Pay attention to the following key points:

Best spray timing

• Early instar stage (1-2 weeks after hatching) gives the best results.
• At this stage, larvae are small, eat little, and have low resistance, so a small amount of insecticide kills them.
• Older larvae eat more and have higher resistance, requiring more insecticide.
• Early detection and early spraying are critical; spraying after leaves are already eaten is too late.

Spraying method

• Spray evenly on both sides of infested leaves.
• Focus on leaf undersides — inchworm larvae often hide there.
• Also spray young shoots and new leaves, which larvae prefer.
• Spray trunks and the ground moderately — inchworms drop down on silk; those that land on treated ground die.
• For tall trees, focus on the lower and middle canopy.

Frequency

• One spray is usually sufficient to control most larvae.
• For severe infestations, reapply after 7-10 days.
• Reapply after rain.

Precautions

• Dinotefuran-containing sprays are toxic to bees and other pollinators; do not spray during flowering.
• Avoid spraying in strong sunlight or windy conditions, which reduce effectiveness. The best time is early morning or evening on clear days.
• Wear gloves and a mask when spraying.
• Use household-strength dinotefuran spray for home orchards and yard trees.
